ZTE (a) and SIR-ZTE (b) imaging pulse sequences. ZTE parameters: 51896 projections, TR = 2 ms, 1 min 43 sec scan time. SIR-ZTE parameters: 6588 projections, TR = 200 ms, 21 min 58 sec scan time. FOV = 64 mm isotropic, resolution = 500 µm isotropic, and 1 signal acquisition for both. The pre-excitation portion of the readout gradient and the short T2* of bound and pore water 1H signal serve to effectively spoil residual transverse magnetization created by the adiabatic pulse.
